The purpose of the function used for the hours to minutes conversion is actually used for converting decimal degrees into latitude and longitude in degrees and minutes and seconds of arc, but using it to convert time is a good way to use it as well.
THANK YOU, THANK YOU. The time into minutes and hours and storing values into a calculator actually saved my life. You're a legend, schools don't even teach us this
Oh my god I've always been a victim of forgetting to put that fraction in for the quadratic formula and then having to start again. You absolute legend!
all AQA Maths 2023 exam students have a paper 2 calculator exam and thanks to you, out of all of the youtube maths tutors, you have literally helped me the most :)
The standard form conversions do work with negative powers - you just need to use the (-) button (under the red Alpha A) between the x10 and the power and it should work.
It also depends how the calculator is set up. If you input a negative power standard form number, press = and you don’t get the decimal you’re hoping for, try pressing SETUP, 8, 2. It should now give you the decimal number 0.0000… (assuming there’s sufficient space for that number to fit on the screen). [This is on the Casio fx-83] 🙂

i have a a maths paper 2 mock exam tmrw, (Im in yr10) and this video helped me so much, i honestly thought i was the master with calculator tricks, this video really humbled me haha! Thank you for the tricks, theyre really useful and will save me alot of time in my exam! (:
Thank you so much. It is literally the night before my last maths exam, and I decided to watch this video and I'm so glad I did. All these tips were so useful and even though I knew I few before, I didn't know any of the more important ones mentioned, like the store feature (which I was actually stressing over earlier, having to writing down long numbers from using things like sine rule without knowing this thing existed). Anyway, thank you so much for making this video because now I feel even more confident for my exam.
Here's a cool thing you can do if you have extra time on your exam: Using the variable assignment function, you can actually record down your answers for MCQ questions by using A, B, C, D, for the various options. Here's my system for doing it, although you can come up with your own. For all questions in MCQ, if the answer is X, store the question number into X. For question numbers over 10, use a decimal mark to seperate them from those lower than 10. For example, suppose questions 1, 4, 7, 12, and 23 have the answer A. I would form the number 147.1223 and store that as A. After the exam, you can compare your answers with others for fun.
Holy crap bro your about to give me 10 free marks thank you so much bro I actually never knew how to do these questions you just made my life so easy bro u don’t even know I love you bro
I used to be in set 9 and was predicted a grade 2 for maths, but then I saw this video and now I am doing my Further Maths a-level course. Thank you so much
@@brainstormmath Matrices are required in IGCSE math b so i thought to mention it also the plotting graphs part was actually mindblowing i didn't know they could do that
On some Casio calcs, such as the fx-85GT CW, there is no FACT button. Instead, you enter the number as normal (although the '=' button is now an 'EXE' button), then press the 'FORMAT' button. This gives a menu that you can choose 'Prime Factor' from, amongst other things.
Hello Hong Konger here. DSE, our equivelent of IB students bring 50 calculators each with pre programmed functions to their math test. (I heard this from my math teacher, I go to international school) It's pretty funny lol.
I got no idea how the heck did this video got recommended for me. Just bought my first scientific calculator an hours ago. I have got my physics olympiad's national round the day after tomorrow. So its a total miracle.
You need yourself a numworks calculator, That really is the best one you are allowed, I assume its allowed at GCSE, it is at A-Level, It can draw graphs and solve equations so easily, they're godlike
THIS WAS DEFINETELY WORTH 8 MINUTES AND 32 SECONDS OF MY TIME, IN FACT IT'S PROBABLY THE MOST USE OF TIME I'VE EVER MADE ON RU-vid 😭😭😭 thank you sooooo much for this, it was insanely helpful! im in yr 10 but it doesn't hurt to know lmfao, but omggg tysmmm that 2nd table one was A LIFESAVERRR, would it work for long-winded equations like 2x^2x+4? (a made up example) 😂 EITHER WAY THANK YOUUU THIS WAS SO USEFUL
YO thanks so much man, i have my Maths Paper 2 calc tommorow and the advice is to use your calculator at all times. I never understood why as they never truly explained until i came across your video. They have been gatekeeping these. Thanks for these tips cause now i will be able to actually use my calc better and finish quicker wid no stress and get those marks. Ps: i only knew 2 so thanks for the other helpful 8!
You are a amazing human being!! Thank you, so much for enlightening me on this, you have no idea how much confusion about my calculator you have cleared up! Thank you! I'm most likely going to watch this 10 times, to memorise your tips! This is a god send!!! Thank you!!!!!
Just finished up Calc 3 and doing Differential Equations currently. Only got a Graphing Calculator because my Mechanical Engineering class required it... I feel like an old man putting my Ti-30x away and trying to work this newfangled device.
this could help me in my resit to sixth form I'm going to fail but is not the end of the world, I still have a second chance. love this type of method on calculators, why don't the school teachers do this for us on a revision?
